Spot Pond freezes at its edges first, and that ring of grey ice is Stoneham's reliable notice that plow season has started in earnest. Boston Landscape Co. runs both sides of the year on this side of the Fells: mowing, trimming and edging through the warm months, leaf cleanups in the fall, then plowing driveways and lots and salting the walks once the coast storms swing inland. Being this close to Boston means wet, dense snow that comes in fast off the water and turns to glaze by morning, so the timing of a route matters as much as the equipment. Nothing beats pulling out of a property at first light knowing the pavement behind you is clean and the path to the door is safe. Come July the same care shows up as a straight cut line and a lawn that holds its color.
